Perhaps you should try some spelling variations:
"neural coding algorithm" » "neural cosine algorithm" (Expand Search), "neural modeling algorithm" (Expand Search), "neural finding algorithm" (Expand Search)
"element box algorithm" » "element best algorithm" (Expand Search), "element _ algorithm" (Expand Search), "element ii algorithm" (Expand Search)
"elements ppo algorithm" » "elements pso algorithm" (Expand Search), "elements two algorithms" (Expand Search), "elements _ algorithm" (Expand Search), "elements ppm algorithm" (Expand Search), "elements upon algorithm" (Expand Search)

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((("element box algorithm") OR ("elements ppo algorithm"))) OR ("neural coding algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"element box algorithm\") OR (\"elements ppo algorithm\"))) OR (\"neural coding algorithm\"))".
• Removing quotes may allow a broader search: (((( element box algorithm ) OR ( elements ppo algorithm ))) OR ( neural coding algorithm )).
• Adding a wildcard symbol may retrieve word variants: (((("element box algorithm") OR ("elements ppo algorithm"))) OR ("neural coding algorithm"))*.
